2x TESLA ECC802S (=E82CC 6189) lk Telefunken, Same 6/1982 Date Codes, *Retail NOS/NIB*, 100%+, 334+335

You are bidding on two pieces of TESLA ECC802S (12AU7WA, E82CC) tubes in NOS/NIB condition! These are industrial-grade tubes made for army or aerospace use, and other demanding applications. Construction-wise, they are similar to the exceedingly expensive Telefunken ECC802S tubes, and some like these even better. Both tubes feature non-corrosive pins, white prints, 32 factory codes, large ribbed plates, copper system and grid posts, and large halo getters. Identical date/batch codes on both: 6/1982. These are never used tubes in original retail boxes (boxes have some damage from stickers and storage), with matching batch numbers on the glass and box flaps! These test as 100%+ and well matched: Tube 1 (334): Ia1= 04.30 mA / Ia2 = 04.90 mA, S/gm1= 01.20 mA/V / S/gm2= 01.40 mA/V Tube 2 (335): Ia1= 04.10 mA / Ia2 = 04.60 mA, S/gm1= 01.20 mA/V / S/gm2= 01.30 mA/V 100% gm/S = 1.0 mA/V, 100% Ia = approx. 3.0 mA. These are rather rare now especially in retail boxes. Very nice tubes! I have more vintage tubes for sale in my other listings. Any number of items can ship in one package, please use the "Add to Cart" button to add multiple items and use checkout to pay only one combined postage. Note on US Tariffs: Starting Aug. 2026, the tariffs on all U.S.-inbound shipments must be pre-paid. The postage price shown includes the 10% tariff, and for this reason, multiple items can no longer ship for one postage price as before, as each item must also include a 10% pre-paid tariff fee. For multiple items, please use the "Add to Cat" functionality, and I'll issue an invoice with one postage (30 USD, this also includes 3rd party fees for processing tariff payments) plus 10% tariff for all included items. Sorry for the inconvenience, but my post office requires I comply with the tariff pre-paid rule. To reiterate: items sold to the USA are Delivered Duty Paid (DDP), and will not require additional tariff payment on arrival as this is already part of the shipping costs.
